Deformation Control of Shield Tunnels Affected by Staged Foundation Pit Excavation: Analytical Method and Case Study

The unloading effect induced by foundation pit excavation leads to soil deformation, which may adversely affect the underlying tunnel. Foundation pit excavation is a three-dimensional (3D) deformation process, whereas most existing methods are based on a two-dimensional (2D) plane assumption. To imp...
